I really enjoy a good Season 1 fic, especially if it gets to the essence of the characters, as yours does. A good Season 1 fic takes on the qualities of a somewhat haunting AU (Billy instead of Aaron; Shannon gets to live; Hurley really does find happiness in love) but in a good way. The fic takes you on a journey of what LOST could have been like, if the point had been more about actually making the characters happy.
